/**
* Client for accessing DynamoDB. All service calls made using this client are blocking, and will not return until the
* service call completes.
*
* Amazon DynamoDB
*
* Amazon DynamoDB is a fully managed NoSQL database service that provides fast and predictable performance with
* seamless scalability. DynamoDB lets you offload the administrative burdens of operating and scaling a distributed
* database, so that you don't have to worry about hardware provisioning, setup and configuration, replication, software
* patching, or cluster scaling.
*
*
* With DynamoDB, you can create database tables that can store and retrieve any amount of data, and serve any level of
* request traffic. You can scale up or scale down your tables' throughput capacity without downtime or performance
* degradation, and use the AWS Management Console to monitor resource utilization and performance metrics.
*
*
* DynamoDB automatically spreads the data and traffic for your tables over a sufficient number of servers to handle
* your throughput and storage requirements, while maintaining consistent and fast performance. All of your data is
* stored on solid state disks (SSDs) and automatically replicated across multiple Availability Zones in an AWS region,
* providing built-in high availability and data durability.

*
* The BatchGetItem operation returns the attributes of one or more items from one or more tables. You
* identify requested items by primary key.
*
*
* A single operation can retrieve up to 16 MB of data, which can contain as many as 100 items.
* BatchGetItem returns a partial result if the response size limit is exceeded, the table's
* provisioned throughput is exceeded, or an internal processing failure occurs. If a partial result is returned,
* the operation returns a value for UnprocessedKeys. You can use this value to retry the operation
* starting with the next item to get.
*
*
*
* If you request more than 100 items, BatchGetItem returns a ValidationException with the
* message "Too many items requested for the BatchGetItem call."
*
*
*
* For example, if you ask to retrieve 100 items, but each individual item is 300 KB in size, the system returns 52
* items (so as not to exceed the 16 MB limit). It also returns an appropriate UnprocessedKeys value so
* you can get the next page of results. If desired, your application can include its own logic to assemble the
* pages of results into one dataset.
*
*
* If none of the items can be processed due to insufficient provisioned throughput on all of the tables in
* the request, then BatchGetItem returns a ProvisionedThroughputExceededException. If
* at least one of the items is successfully processed, then BatchGetItem completes
* successfully, while returning the keys of the unread items in UnprocessedKeys.
*
*
*
* If DynamoDB returns any unprocessed items, you should retry the batch operation on those items. However, we
* strongly recommend that you use an exponential backoff algorithm. If you retry the batch operation
* immediately, the underlying read or write requests can still fail due to throttling on the individual tables. If
* you delay the batch operation using exponential backoff, the individual requests in the batch are much more
* likely to succeed.
*
*
* For more information, see Batch
* Operations and Error Handling in the Amazon DynamoDB Developer Guide.
*
*
*
* By default, BatchGetItem performs eventually consistent reads on every table in the request. If you
* want strongly consistent reads instead, you can set ConsistentRead to true for any or
* all tables.
*
*
* In order to minimize response latency, BatchGetItem retrieves items in parallel.
*
*
* When designing your application, keep in mind that DynamoDB does not return items in any particular order. To
* help parse the response by item, include the primary key values for the items in your request in the
* ProjectionExpression parameter.
*
*
* If a requested item does not exist, it is not returned in the result. Requests for nonexistent items consume the
* minimum read capacity units according to the type of read. For more information, see Working with Tables in the Amazon DynamoDB Developer Guide.
*
*
* @param batchGetItemRequest
* Represents the input of a BatchGetItem operation.
* @return Result of the BatchGetItem operation returned by the service.
* @throws ProvisionedThroughputExceededException
* Your request rate is too high. The AWS SDKs for DynamoDB automatically retry requests that receive this
* exception. Your request is eventually successful, unless your retry queue is too large to finish. Reduce
* the frequency of requests and use exponential backoff. For more information, go to Error Retries and Exponential Backoff in the Amazon DynamoDB Developer Guide.
* @throws ResourceNotFoundException

* The BatchWriteItem operation puts or deletes multiple items in one or more tables. A single call to
* BatchWriteItem can write up to 16 MB of data, which can comprise as many as 25 put or delete
* requests. Individual items to be written can be as large as 400 KB.
*
*
*
* BatchWriteItem cannot update items. To update items, use the UpdateItem action.
*
*
*
* The individual PutItem and DeleteItem operations specified in
* BatchWriteItem are atomic; however BatchWriteItem as a whole is not. If any requested
* operations fail because the table's provisioned throughput is exceeded or an internal processing failure occurs,
* the failed operations are returned in the UnprocessedItems response parameter. You can investigate
* and optionally resend the requests. Typically, you would call BatchWriteItem in a loop. Each
* iteration would check for unprocessed items and submit a new BatchWriteItem request with those
* unprocessed items until all items have been processed.
*
*
* If none of the items can be processed due to insufficient provisioned throughput on all of the tables in
* the request, then BatchWriteItem returns a ProvisionedThroughputExceededException.
*
*
*
* If DynamoDB returns any unprocessed items, you should retry the batch operation on those items. However, we
* strongly recommend that you use an exponential backoff algorithm. If you retry the batch operation
* immediately, the underlying read or write requests can still fail due to throttling on the individual tables. If
* you delay the batch operation using exponential backoff, the individual requests in the batch are much more
* likely to succeed.
*
*
* For more information, see Batch Operations and Error Handling in the Amazon DynamoDB Developer Guide.
*
*
*
* With BatchWriteItem, you can efficiently write or delete large amounts of data, such as from Amazon
* EMR, or copy data from another database into DynamoDB. In order to improve performance with these large-scale
* operations, BatchWriteItem does not behave in the same way as individual PutItem and
* DeleteItem calls would. For example, you cannot specify conditions on individual put and delete
* requests, and BatchWriteItem does not return deleted items in the response.
*
*
* If you use a programming language that supports concurrency, you can use threads to write items in parallel. Your
* application must include the necessary logic to manage the threads. With languages that don't support threading,
* you must update or delete the specified items one at a time. In both situations, BatchWriteItem
* performs the specified put and delete operations in parallel, giving you the power of the thread pool approach
* without having to introduce complexity into your application.
*
*
* Parallel processing reduces latency, but each specified put and delete request consumes the same number of write
* capacity units whether it is processed in parallel or not. Delete operations on nonexistent items consume one
* write capacity unit.
*
*
* If one or more of the following is true, DynamoDB rejects the entire batch write operation:
*
*
* -
*
* One or more tables specified in the BatchWriteItem request does not exist.
*
*
* -
*
* Primary key attributes specified on an item in the request do not match those in the corresponding table's
* primary key schema.
*
*
* -
*
* You try to perform multiple operations on the same item in the same BatchWriteItem request. For
* example, you cannot put and delete the same item in the same BatchWriteItem request.
*
*
* -
*
* Your request contains at least two items with identical hash and range keys (which essentially is two put
* operations).
*
*
* -
*
* There are more than 25 requests in the batch.
*

* Creates a backup for an existing table.
*
*
* Each time you create an on-demand backup, the entire table data is backed up. There is no limit to the number of
* on-demand backups that can be taken.
*
*
* When you create an on-demand backup, a time marker of the request is cataloged, and the backup is created
* asynchronously, by applying all changes until the time of the request to the last full table snapshot. Backup
* requests are processed instantaneously and become available for restore within minutes.
*
*
* You can call CreateBackup at a maximum rate of 50 times per second.
*
*
* All backups in DynamoDB work without consuming any provisioned throughput on the table.
*
*
* If you submit a backup request on 2018-12-14 at 14:25:00, the backup is guaranteed to contain all data committed
* to the table up to 14:24:00, and data committed after 14:26:00 will not be. The backup might contain data
* modifications made between 14:24:00 and 14:26:00. On-demand backup does not support causal consistency.
*
*
* Along with data, the following are also included on the backups:
*
*
* -
*
* Global secondary indexes (GSIs)
*
*
* -
*
* Local secondary indexes (LSIs)
*
*
* -
*
* Streams

/**
*
* Creates a global table from an existing table. A global table creates a replication relationship between two or
* more DynamoDB tables with the same table name in the provided Regions.
*
*
*
* This operation only applies to Version
* 2017.11.29 of global tables.
*
*
*
* If you want to add a new replica table to a global table, each of the following conditions must be true:
*
*
* -
*
* The table must have the same primary key as all of the other replicas.
*
*
* -
*
* The table must have the same name as all of the other replicas.
*
*
* -
*
* The table must have DynamoDB Streams enabled, with the stream containing both the new and the old images of the
* item.
*
*
* -
*
* None of the replica tables in the global table can contain any data.
*
*
*
*
* If global secondary indexes are specified, then the following conditions must also be met:
*
*
* -
*
* The global secondary indexes must have the same name.
*
*
* -
*
* The global secondary indexes must have the same hash key and sort key (if present).
*
*
*
*
* If local secondary indexes are specified, then the following conditions must also be met:
*
*
* -
*
* The local secondary indexes must have the same name.
*
*
* -
*
* The local secondary indexes must have the same hash key and sort key (if present).
*
*
*
*
*
* Write capacity settings should be set consistently across your replica tables and secondary indexes. DynamoDB
* strongly recommends enabling auto scaling to manage the write capacity settings for all of your global tables
* replicas and indexes.
*
*
* If you prefer to manage write capacity settings manually, you should provision equal replicated write capacity
* units to your replica tables. You should also provision equal replicated write capacity units to matching
* secondary indexes across your global table.

/**
*
* Returns the current provisioned-capacity limits for your AWS account in a Region, both for the Region as a whole
* and for any one DynamoDB table that you create there.
*
*
* When you establish an AWS account, the account has initial limits on the maximum read capacity units and write
* capacity units that you can provision across all of your DynamoDB tables in a given Region. Also, there are
* per-table limits that apply when you create a table there. For more information, see Limits page in the
* Amazon DynamoDB Developer Guide.
*
*
* Although you can increase these limits by filing a case at AWS Support Center, obtaining the increase is not
* instantaneous. The DescribeLimits action lets you write code to compare the capacity you are
* currently using to those limits imposed by your account so that you have enough time to apply for an increase
* before you hit a limit.
*
*
* For example, you could use one of the AWS SDKs to do the following:
*
*
* -
*
* Call DescribeLimits for a particular Region to obtain your current account limits on provisioned
* capacity there.
*
*
* -
*
* Create a variable to hold the aggregate read capacity units provisioned for all your tables in that Region, and
* one to hold the aggregate write capacity units. Zero them both.
*
*
* -
*
* Call ListTables to obtain a list of all your DynamoDB tables.
*
*
* -
*
* For each table name listed by ListTables, do the following:
*
*
* -
*
* Call DescribeTable with the table name.
*
*
* -
*
* Use the data returned by DescribeTable to add the read capacity units and write capacity units
* provisioned for the table itself to your variables.
*
*
* -
*
* If the table has one or more global secondary indexes (GSIs), loop over these GSIs and add their provisioned
* capacity values to your variables as well.
*
*
*
*
* -
*
* Report the account limits for that Region returned by DescribeLimits, along with the total current
* provisioned capacity levels you have calculated.
*
*
*
*
* This will let you see whether you are getting close to your account-level limits.
*
*
* The per-table limits apply only when you are creating a new table. They restrict the sum of the provisioned
* capacity of the new table itself and all its global secondary indexes.
*
*
* For existing tables and their GSIs, DynamoDB doesn't let you increase provisioned capacity extremely rapidly. But
* the only upper limit that applies is that the aggregate provisioned capacity over all your tables and GSIs cannot
* exceed either of the per-account limits.
*
*
*
* DescribeLimits should only be called periodically. You can expect throttling errors if you call it
* more than once in a minute.
*
*
*
* The DescribeLimits Request element has no content.
*
*
* @param describeLimitsRequest

* Creates a new item, or replaces an old item with a new item. If an item that has the same primary key as the new
* item already exists in the specified table, the new item completely replaces the existing item. You can perform a
* conditional put operation (add a new item if one with the specified primary key doesn't exist), or replace an
* existing item if it has certain attribute values. You can return the item's attribute values in the same
* operation, using the ReturnValues parameter.
*

*
* This topic provides general information about the PutItem API.

*
* When you add an item, the primary key attributes are the only required attributes. Attribute values cannot be
* null.
*
*
* Empty String and Binary attribute values are allowed. Attribute values of type String and Binary must have a
* length greater than zero if the attribute is used as a key attribute for a table or index. Set type attributes
* cannot be empty.
*
*
* Invalid Requests with empty values will be rejected with a ValidationException exception.
*
*
*
* To prevent a new item from replacing an existing item, use a conditional expression that contains the
* attribute_not_exists function with the name of the attribute being used as the partition key for the
* table. Since every record must contain that attribute, the attribute_not_exists function will only
* succeed if no matching item exists.

/**
*
* The Query operation finds items based on primary key values. You can query any table or secondary
* index that has a composite primary key (a partition key and a sort key).
*
*
* Use the KeyConditionExpression parameter to provide a specific value for the partition key. The
* Query operation will return all of the items from the table or index with that partition key value.
* You can optionally narrow the scope of the Query operation by specifying a sort key value and a
* comparison operator in KeyConditionExpression. To further refine the Query results, you
* can optionally provide a FilterExpression. A FilterExpression determines which items
* within the results should be returned to you. All of the other results are discarded.
*
*
* A Query operation always returns a result set. If no matching items are found, the result set will
* be empty. Queries that do not return results consume the minimum number of read capacity units for that type of
* read operation.
*
*
*
* DynamoDB calculates the number of read capacity units consumed based on item size, not on the amount of data that
* is returned to an application. The number of capacity units consumed will be the same whether you request all of
* the attributes (the default behavior) or just some of them (using a projection expression). The number will also
* be the same whether or not you use a FilterExpression.
*
*
*
* Query results are always sorted by the sort key value. If the data type of the sort key is Number,
* the results are returned in numeric order; otherwise, the results are returned in order of UTF-8 bytes. By
* default, the sort order is ascending. To reverse the order, set the ScanIndexForward parameter to
* false.
*
*
* A single Query operation will read up to the maximum number of items set (if using the
* Limit parameter) or a maximum of 1 MB of data and then apply any filtering to the results using
* FilterExpression. If LastEvaluatedKey is present in the response, you will need to
* paginate the result set. For more information, see Paginating
* the Results in the Amazon DynamoDB Developer Guide.
*
*
* FilterExpression is applied after a Query finishes, but before the results are
* returned. A FilterExpression cannot contain partition key or sort key attributes. You need to
* specify those attributes in the KeyConditionExpression.
*
*
*
* A Query operation can return an empty result set and a LastEvaluatedKey if all the
* items read for the page of results are filtered out.
*
*
*
* You can query a table, a local secondary index, or a global secondary index. For a query on a table or on a local
* secondary index, you can set the ConsistentRead parameter to true and obtain a strongly
* consistent result. Global secondary indexes support eventually consistent reads only, so do not specify
* ConsistentRead when querying a global secondary index.
*

/**
*
* TransactWriteItems is a synchronous write operation that groups up to 25 action requests. These
* actions can target items in different tables, but not in different AWS accounts or Regions, and no two actions
* can target the same item. For example, you cannot both ConditionCheck and Update the
* same item. The aggregate size of the items in the transaction cannot exceed 4 MB.
*
*
* The actions are completed atomically so that either all of them succeed, or all of them fail. They are defined by
* the following objects:
*
*
* -
*
* Put — Initiates a PutItem operation to write a new item. This structure
* specifies the primary key of the item to be written, the name of the table to write it in, an optional condition
* expression that must be satisfied for the write to succeed, a list of the item's attributes, and a field
* indicating whether to retrieve the item's attributes if the condition is not met.
*
*
* -
*
* Update — Initiates an UpdateItem operation to update an existing item. This
* structure specifies the primary key of the item to be updated, the name of the table where it resides, an
* optional condition expression that must be satisfied for the update to succeed, an expression that defines one or
* more attributes to be updated, and a field indicating whether to retrieve the item's attributes if the condition
* is not met.
*
*
* -
*
* Delete — Initiates a DeleteItem operation to delete an existing item. This
* structure specifies the primary key of the item to be deleted, the name of the table where it resides, an
* optional condition expression that must be satisfied for the deletion to succeed, and a field indicating whether
* to retrieve the item's attributes if the condition is not met.
*
*
* -
*
* ConditionCheck — Applies a condition to an item that is not being modified by the
* transaction. This structure specifies the primary key of the item to be checked, the name of the table where it
* resides, a condition expression that must be satisfied for the transaction to succeed, and a field indicating
* whether to retrieve the item's attributes if the condition is not met.
*
*
*
